Abstract

Fluorosis levels and caries prevalence were evaluated in 152 children aged 6-8 yr residing from birth in an area with 5 ppm fluoride in the drinking water. Sixty-two of the subjects had mild fluorosis in both primary and permanent dentition, 31 were defined as moderate, and 4 cases had no signs of fluorosis; 14 cases had a more severe fluorosis level in the primary dentition as compared to 41 cases in which fluorosis was more severe in the permanent dentition. More primary dentitions were free of fluorosis in females than in males (P less than 0.05). No differences between males and females were found in the permanent dentition fluorosis. The decay rate in the permanent dentition gradually increased with increasing fluorosis severity, a finding not observed in the primary dentition. Reasons are discussed for the lower fluorosis level in the primary dentition and the more severe fluorosis in older age groups as well as the fluorosis severity difference by gender.

    OBJECTIVE: The aim of this study was to investigate the caries prevalence of children living in either low- or high-fluoride areas and to relate caries experience to the severity of dental fluorosis. METHOD AND MATERIALS: A total of 278 12- to 14-year-old schoolchildren, 149 in a low-fluoride area (LFA) and 129

  • Dental Fluorosis and Dental Caries.

    FOR some 8 or 9 years past the presence of fluorine in water supplies has been attracting much attention, chiefly as a danger and as the cause of endemic dental fluorosis, or mottled enamel, which has been reported in some 300 communities in 23 states of the Union. According to Dean,1

  • Characteristics of epidemiology of dental caries in children from regions with high and optimum fluorine content in drinking water.

    Objective: Introduction: Prevention of dental diseases in children is the priority item on the modern dentistry agenda. Among the undeniable factors known as contributing into caries incidence, there is fluoride content in the external environment, especially in drinking water, which is the main source of fluoride intake. The aim: This

  • Moderate/Severe Dental Fluorosis

    In its "moderate" and severe forms, fluoride causes a marked increase in the porosity of the enamel. After eruption into mouth, the porous enamel of moderate to severe fluorosis readily takes up stain, creating permanent brown and black discolorations of the teeth. In addition to extensive staining, teeth with moderate to severe fluorosis are more prone to attrition and wear - leading to pitting, chipping, and decay.

  • "Mild" Dental Fluorosis: Perceptions & Psychological Impact

    The vast majority of research has found that patients, parents, and the general public alike view mild fluorosis (TF score 3) as a significant blemish of the teeth, one that is likely to embarrass the affected child to a degree that cosmetic treatment would be warranted.

    The traditional criteria (the "Dean Index") for diagnosing dental fluorosis was developed in the first half of the 20th century by H. Trendley Dean.

  • Dental Fluorosis Impacts Dentin in Addition to Enamel

    Dental fluorosis is a mineralization defect of tooth enamel marked by increased subsurface porosity. The enamel, however, is not the only component of teeth that is effected. As several studies have demonstrated, dental fluorosis can also impair the mineralization of dentin as well. As noted in one review: "The fact that
